That is because the fluoride ion has 8 electrons and 9 protons while a lithium ion has 3 protons and 3 electrons. Therefore the lithium ion has fewer shells than flouride
Answer:
The given statement is true.
Explanation:
Strong acids and bases act as strong electrolytes.They undergo complete dissociation in an aqueous medium to generate cations and anions.
For example HCl ⇄ H+ + Cl-
Hydrochloric acid is a strong electrolyte,it undergo complete dissociation in an aqueous solution to generate H+ ion and Cl- ion.
On the other hand acetic acid is a weak acid and act as weak electrolyte.In aqueous solution acetic acid under partial dissociation to form acetate anion and proton.
CH3COOH ⇄ CH3COO- + H+
Answer:
CCl4 - Nonpolar
CH3OH - polar
NH3 - polar
CS2 - Nonpolar
Explanation:
One important thing that we should know is that polarity has to do with the presence of a resultant dipole moment in a molecule.
Dipole moment is a vector quantity, This means that its direction is also taken into account when discussing the dipole moment of molecules.
Hence, symmetrical molecules such as CS2 and CCl4 are non-polar even though they have polar bonds because their dipoles cancel out(zero resultant dipole moment).
On the other hand, NH3 and CH3OH are non-symmetrical molecules hence they possess an overall dipole moment and are polar molecules.
This problem is providing us with the mass of hydrochloric acid and the volume of solution and asks for the pH of the resulting solution, which turns out to be 1.477.
<h3>pH calculations</h3>
In chemistry, one can calculate the pH of a solution by firstly obtaining its molarity as the division of the moles of solute by the liters of solution, so in this case for HCl we have:
Next, due to the fact that hydrochloric acid is a strong acid, we realize its concentration is nearly the same to the released hydrogen ions to the solution upon ionization. Thereby, the resulting pH is:
Which conserves as much decimals as significant figures in the molarity.
